I am probably the most undisciplined investor in this thread. My first investment property was my second house, about six blocks from my primary. I did a 15 year mortgage to encourage equity accumulation and put 20% down as a true investment property. I rented for $1,500 per month against a $1,580 monthly payment which includes principal, interest, taxes, and insurance. To make matters worse and further upset the cash flow investors, I also have a property manager for 8%.
So, you could say, I did a lot wrong with this property. I've subsidized the mortgage $120 per month for 60 months. I paid out of pocket for a new air conditioning unit, landscape renovations/repairs, appliance repairs, etc to the tune of about $10,000 in five years. However, in having the same tenant for four plus years, they've never missed a payment and I've never had a vacancy. While a vacancy would get me up to market rents (~$2,000 today), I still have $0 vacancy loss in four years at least. I've paid about $17,200 out of this pocket in five years, or more than $3,000 per year.
However, the last prong is appreciation. I benefited from a fee appraisal last fall that documented 41% appreciation from purchase in about four and a half years. Combined with the dramatic 15 year mortgage pay down, I was able to secure a HELOC for about five times my out of pocket during my time of ownership. Stated another way, the HELOC returned my down payment, closing costs, mortgage supplements, and all repairs improvements in about five years.
The big difference is, this property is in the Kierland area of North Scottsdale, and not Las Vegas. My concern in your market is the values have still not fully recovered as I understand nor has the inventory fully absorbed. As such, how long will that take, and what will it look like for you by the time it does?
Good luck, investing is very personal, but the results are very objective. Make sure the numbers work, and you can afford your worst case scenario.
